IMPROVEMENT IN SUPPLVING STEAM TO TRAVELING ENGINES.

Specication forming part of Letters Patent No. 129,969, dated July 30,1872.

To all whom t may concern:

Be it known that I, EMILE LAMM, of the city of New Orleans, parish ofOrleans, State of Louisiana, have invented a new and Improved Mode orProcess of SuperheatinglVater in the Thermo-Specific Engine, of which'the following is a full and exact description:

The object of my invention is to heat above the atmospheric pressurewater contained in a close vessel or `reservoir on a street-car or othervehicles by means of the condensation of steam in the above-namedreservoir, the steam having previously been generated under pressure ina stationary boiler. By this process I avoid discharging the lwater onthe car, the temperature of which was lowered by the steam expended inworking the engine during the trip. Thus, instead of replacing this samewater in the reservoir by other and hotter water taken from thestationary boiler, I cause steam of the required temperature to rushinto and condense in the reservoir until the pristine force or heat ofthe water is restored. v By reference to the drawing and letters thereonmy invention can be easily understood.

Figure l is a longitudinal section.'

A is the reservoir on the car. W W denote the water-line. B is an irontube, boltedthrough the heads of A. This tube is closed at one end, andat the other end is provided with both a throttle-valve, G, and theone-half of a union coupling, D. This same tube is perforated inside thereservoir by anumber of small holes,

' the apertures of which are turned downward.

The holes are placed about six inches apart through the whole interiorlength ofthe tube. The-ir total area should equal that of a crosssectionof the tube.

" The manner in which my invention operates the end of the tube B isconnected, by means a stationary boiler. As soon as communicationbecomes established, by the proper openon the car and the stationaryboiler, the steam from said boiler rushes into the reservoir, and by itscondensation, which begins at the bottom of the'water, heats the wholeof it upward and in an equal degree throughout the entire Witnesses:
